I am a product engineer with a frontend lean, about seven years in, mostly on developer tools. Most recently I set up the developer experience and tooling at Composio: the TypeScript and Python SDKs from zero, now past 1M weekly npm downloads, plus the provider adapters into OpenAI, the Vercel AI SDK and LangChain, the dashboard and auth layer across 1000+ apps, and the metering behind a million events a day. The piece I am proudest of is the agent CLI, a surface designed for an agent consumer rather than a human one, which cut token use 60 to 70 percent per task.
Before that, six years at Locale.ai. I joined as a founding engineer and built the frontend that rendered large geospatial datasets in the browser, dashboards over millions of rows for enterprise mobility and delivery companies. As lead product engineer I owned design, build and releases, and led a team across frontend, backend and platform

About: Senior software engineer with extensive experience in building, and leading product and engineering teams. I have great design sense, and have been designing and shipping products for the last 8+ years. I have worked with several companies in their 0-1 journey, and 0-Mil journey as well, from idea to production. I have been working as a senior software engineer at Composio, where I have built the SDKs, APIs, and developer platfrom for the company which allows developers to integrate and build 1000s of integrations into their agents. I have strong typescript knowledge, with experience in building top-class SDKs, APIs, Interfaces and Kickass Developer Experience and Agent Experience.
I'm looking for early/mid stage companies to help them build best in class products. Looking for product engineering / full-stack engineering + SWE or Design Engineering role.
